Spent Jetboil fuel canisters are recyclable as long as you use the CrunchIt Fuel Cansiter Recycling Tool to safely vent the pressurized butane before you toss them in the appropriate bin. Reduce your impact on the planet that you live to explore with this can-opener-shaped tool. Designed to relieve the pressure from your butane Jetpower canisters (and some similar models) and easily puncture the housing with the CrunchIt's sharp stainless steel tooth. Then you can recycle it as tin or steel with most local programs.
